this is matlab small programming for compare the graphic with color

jpeg在matlab下的实现详细过程，有需要的朋友请下载(jpeg in matlab to achieve under the process in detail, there is a need friends please download)

对于一维各向异性问题，这里利用阻尼最小二乘的反演算法，结合RI反演数据集反演。(For one-dimensional anisotropic problems, where the use of damped least squares inversion algorithm, combined with the RI data set inversion inversion.)

线性调频信号的部分功能 线性调频信号的部分功能(range_migration range_migration)

运动目标识别，采用背景差分方法。背景图像由均值法获得。里面的视频换成前几帧换成纯背景效果能更好一点(Moving target identification, using the background difference method. Background image obtained from the mean. Which replaced the previous video frame replaced by pure background a little better results)

由设计要求可知，wp<=0.2π，允许误差幅度小于1dB，ws>=0.3π内衰减应大于15dB。为了验证数字滤波器的实际滤波功能，设计程序时，把输入序列定为验证函数x（t）=4sin（100πt）以及x（t）=4sin（200πt）和x（t）=4sin（400πt）。又因为Ts=1.25ms，T=80ms，故采样点为64，即N=64，所以当M=6，可以同时调试并验证程序的滤波功能。(Seen by the design requirements, wp < = 0.2π, allow a margin of error of less than 1dB, ws> = 0.3π within attenuation greater than 15dB. In order to verify the actual filtering function of the digital filter design program, the input sequence as validation function x (t) = 4sin (100πt) and x (t) = 4sin (200πt) and x (t) = 4sin (400πt) . And because Ts = 1.25ms, T = 80ms, so the sampling points is 64, that is N = 64, so when M = 6, can debug and validate filtering program.)

只要输入低通滤波器系数，可画有负数尺度的多尺度函数的图象(As long as the importation of low-pass filter coefficient, can be painted a negative multi-scale image scaling function)

LMS和RLS的M文件源码，还有回应对消系统的LMS和RLS的M文件源码(LMS and RLS M-file source, and respond to cancellation system, the LMS and RLS M-file source)

实现扩频CDMA系统的仿真，并实现不同用户数下误码率的输出(can present the simulation of dsCDMA)

说明：  elm算法，我做风电功率预测时用到过，比较好用。(Elm algorithm, I do wind power prediction used, relatively easy to use.)
